my baby is 13 weeks old. he's pretty manageable in the day time. he takes pretty short naps in the day (typically ranging from 15 mins to 30 mins). of late, he gets really cranky and cries and fusses a lot during the night (aftr 8pm). any reason why?
your baby is overtired. 15-30 mins naps are insufficient. they need to sleep at least 1-2.5h for each nap. you need to push bedtime earlier.
once they know how to sleep on their own and connect sleep cycles through self soothing, they can nap long. the only way to do this is through sleep training. our babies have the ability to sleep independently, they just need to learn on their own.
